The great french chemist antoine lavoisier discovered the law of conservation of mass in part by doing a famous experiment in 1775. in this experiment lavoisier found that mercury(ii) oxide, when heated, decomposed into liquid mercury and an invisible and previously unknown substance: oxygen gas.
1. write a balanced chemical equation, including physical state symbols, for the decomposition of solid mercury(ii) oxide (hgo) into liquid mercury and gaseous dioxygen.
2. suppose 50.0ml of dioxygen gas are produced by this reaction, at a temperature of 90°c and pressure of exactly 1atm. calculate the mass of mercury(ii) oxide that must have reacted. be sure your answer has the correct number of significant digits.

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.
